IMPROVEMENT IN LOCKHI'NGES.

Specification forming part of Letters Patent No. 182,570, datedSeptember 26, 1876; application filed August 23, 1876.

To all whom it may concern:

Beit known that I, CHARLES J. FERGUSON, of the city and county ofPhiladelphia, State of Pennsylvania, have invented a new and usefulImprovement in Door and Shutter Hinges, for locking doors and shuttersback, commonly called ShutterFasteners; and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying draw-' ings, making part hereof.

My invention consists of the hereinafter-dc scribed lock-hinge,consisting of a pintle, to the top of which is pivoted a latch orcrosspiece, resting in a slot, in combination with an eye or socket,having one or more vertical slots, with which the said latchautomatically engages, all substantially as hereinafter more fullydescribed and definitely claimed.

To enableothers skilled in the art to make and use my invention, I willdescribe its construction and operation.

In the drawings, Figure 1 is a perspective View of my invention, showingthe shutter partly opened, but not far enough for the latch to fall intothe slot. Fig. 2 shows the shutter opened to the full width, and thelock or latch set in the slot. Fig. 3 is a vertical section of thestandard-bar, showing a peaked stop, which impinges against the heel oflatch on one side to prevent its falling backward and locking theshutter when the latter is closed.

A is the pintle or pivot of the hinge; B, the latch, pivoted at G D, thepeaked rest, under one side of the heel of the latch, to prevent thelatter falling the wrong way,'to wit, backward. E is that arm of thehinge which is driven into or attached to the window-frame, and is inone piece with the pintle A. G is the swinging arm of the hinge, towhich the shutter is attached. H is the eye, attached to the arm G,which clasps the pintle or pivot A. I is a vertical slot in this eye H,to receive the latch B. The pintle A has a slot commencing at its topand continuing down its middle until it ends in the peak or tongue D,The latch B is so pivoted in this slot that its heel rests on one sideof this peak when the latch is not operating, for the reasons namedabove.

The operation is as follows: The drawings show that hinge of theshutters which is to the left looking from the window. When the shutteris closed the slot I is on that side of pintle A opposite to that towhich the latch B is shown to incline, and when, by opening the shuter,a full half-turn is given to the eye H, the slot I is brought oppositeto the slot in the pintle A upon the other side, however; then, as thelatch is heavier above its pivot than beneath it, and as it inclinestoward the present position of slot I, it falls into this slotautomatically and locks the hingein its then position, consequentlykeeping the shutter back without the aid of the old-fashionedturnbuckle.

When the latch B is not in slot I itis sustained in its nearly uprightposition by the upper rim of the eye H. The eye H may be no ched orslotted at other points of its upper rim so as to hold the shutter atvarious angles, but in many casessnch a course would make it diflicultto open the latch again, as there might be a necessity of passing thefingers between the jamb and the shutter to unlatch it, and the openingin some shutters is too narrow to do this. When the shutter is thrownback all the way the latch is left clear to be lifted by its projectin gend out of slot 1, and the shutter can then be closed.

It can be seen that the latch might be placed in the slot I in the eyeH, so that at a certain point it would fall into a notch in the upperedge, or on one side of the upper part of the pintle A; or, there mightbe a series of openings in the side of pintle A corresponding toopenings in the side of eye H, and a pin attached to the hinge or to thewindow frame or shutter by a chain could be passed through a hole in eyeH and into the corresponding one in the pintle A; but, for simplicityand perfect and automatic locking,

I prefer the device which I have shown in the drawings.

Having thus described my invention, what tical slots, I, with which thelatch automatic I claim as new, and desire to secure by Letally engages,all substantially as and for the ters Patent, is purpose set forth.
